Molten aluminum to provide heat + power to developing regions

Solar Media‚Äôs Energy Storage Summit was seriously lacking space for innovators last week, but we did come across a few smaller companies like Azelio, which claims that molten aluminum storage can offer a combination of low-cost heat energy and electricity, which is well adapted for developing regions where solar irradiation is high. The technology aims to enter the market for small-scale storage for microgrids where both electricity and heat are required outside peak hours of generation. This inherently lends itself to complementing solar power in regions which require overnight generation. Typical thermal solutions such as molten salt, require reasonable scale to become feasible; heat storage capacity becomes more efficient as volume increases with capacity at a greater rate than surface…
